Jenneke, 20, bragged about her geographical location -- and her toned body -- when she posted a photo of herself posing next to a beach sign with her nickname on the image sharing site.
"Shelly Beach #beach #sun #summer," she captioned the photo.
Jenneke is currently in Australia, where it's late spring in December. But because many of her fans live in the northern hemisphere were temperatures have been frigid, many took to social media to express their jealousy and compliment her on her stunning physic.
"Wtf?! Its freezing here!!! Lucky [expletive] Australians...," lordldx commented on her photo.
"Hope you had your sun screen on Michelle. That said you look fantastic!" added nmkevinb.
"I need to move fast to Australia. ;-)," wrote fsimpson22.
Jenneke became something of an Internet sensation since her race at the 2012 World Junior Championships in Athletics in Barcelona went viral on YouTube. You can check out the clip below.
